Dr. Miao is a professor in the Department of Physics and Astronomy and California NanoSystems Institute (CNSI) at UCLA. He is also the Deputy Director of STROBE, an NSF Science and Technology Center on Real-Time Functional Imaging, which aims to tackle major scientific challenges by improving imaging technologies. Dr. Miao's research interests lie in the interplay of physics, materials science, nanoscience, and biology. He has developed groundbreaking physical methods for high-resolution 3D imaging of nanoscale materials and biological specimens. He pioneered coherent diffraction imaging (CDI), a lensless imaging (or computational microscopy) technique that is under rapid development worldwide. Recently, he pioneered atomic electron tomography (AET) for 3D structure determination of crystal defects and disordered systems at the single-atom level. Using advanced electron microscopies, X-ray free electron lasers, high harmonic generation, and synchrotron radiation, his group will continue to push the frontiers of high-resolution 3D X-ray and electron imaging and to pursue their applications in the physical and biological sciences.

Jihan Zhou received his B. S. in Chemistry from Peking University in 2009. After that, he studied polymer physics & peptide-mediated siRNA delivery system under the supervision by Prof. Dehai Liang and received his Ph. D. from Peking University in 2014. From Aug 2011 to Apr 2012, he worked in Prof. Sonia Contera’s Biophysics Group at Oxford University as a Visiting Scholar studying liposome mechanics. He joined in the Miao group at UCLA as a Postdoctoral Fellowship in September 2014. His research interest lies in atomic electron tomography (AET) of nanomaterials such as nanoalloy catalysts, metal-semiconductor interfaces and quasi/amorphous materials.
Yongsoo joined the Coherent Imaging Group in Oct. 2014. He received B.S. in Physics and Mathematical science from Seoul National University in 2009, and Ph.D. in experimental condensed matter physics from the University of Michigan in 2014. He has been mainly working on structural determination beyond conventional crystallography, to resolve 3D atomic structure of materials with surface/interface or defects where perfect crystal symmetry is broken.
Dr. Xuezeng Tian joined the Miao Group in January 2017. He was born in Baoding, China and graduated from Shandong University in 2009 with B.S. in Physics. After that he obtained his Ph. D. from the Institute of Physics, Chinese Academy of Sciences in 2014. During his Ph.D., he worked on in situ electrical/optical TEM with Prof. Xuedong Bai, targetting the mechanism of various resistive memories. After that, he became a research fellow in a joint program between the National University of Singapore and UC Berkeley, working towards imaging of dynamics in nanomaterials and biological samples alive with in situ liquid cell TEM. During his past research, he has become proficient in electron microscopy (theory, experiments and image processing), thin films & nanomaterials (preparation and characterization), micro fabrication techniques, and in situ technologies (electrical, thermal, optical and liquid cells). His main research interest lies in atomic electron tomography (AET) of catalytic nanomaterials, to correlate their stability and catalytic properties with their 3D atomic arrangements. His long-term interest is to combine his in situ expertise with the AET method.
Dennis received his B.S. in Chemistry from the University of Massachusetts Amherst in 2011. He received his Ph.D. in Materials Science from the California Institute of Technology in 2017 investigating materials thermodynamics using inelastic neutron scattering and ab initio computational methods. He joined the Coherent Imaging Group as the STROBE postdoctoral fellow in the summer of 2017 and plans to utilize the group's recent advances in imaging techniques to study various materials and their properties.
AJ joined the Miao group in early 2014 as a 1st year physics graduate student. He completed his B.S. in physics at the Georgia Institute of Technology in 2013 and received an M.S. in physics from UCLA in 2015. AJ's interest and expertise lie in algorithm development, computational methods, and end-to-end scientific software design. He believes that there is an art behind developing powerful science, and a science behind the art of proper software design, and he strives to exist at the intersection of intuition, efficiency, and clarity of expression. A notable group contribution was the development of GENFIRE, a state-of-the-art technique for 3D image reconstruction, from the ground up including introduction of novel algorithm concepts and programming of the final GUI. In addition to imaging physics, AJ is interested in high performance computing, computer architecture, machine learning, and the guitar. In his spare time, AJ is an avid football fan and spends time with his wife, daughter, and Beagle.
Arjun received his B.S. in Physics from Rutgers University in 2011. He joined the Miao group in the spring of 2014 and received his M.S. in Physics from UCLA in 2015. Arjun’s main interests lie in algorithm development and hardware design. Currently, he is working on the development of new CDI methods. His hobbies include snowboarding and riding his motorcycle.
Mike joined Miao group in 2015 as a graduate student. As a bioengineer in training, he is interested in the intersection of high resolution imaging science and their applications in medicine and bioengineering. His research focus in coherent diffractive imaging has led him to develop novel ways to capture and analyze high resolution dynamic information from organic and inorganic specimens. With this new technique, he hopes to push the spatiotemporal resolution limits of diffractive imaging to reveal never-before-seen phenomena. Outside of research, Mike is interested in algorithm development, machine learning, design and arts, as well as the game of basketball.
Yao joined the Coherent Imaging Group in March 2017 as a graduate student. He received B.S. degree in Materials Science and Engingeering from Tsinghua University in 2015. He is interested in the 3D reconstruction of materials by combining advanced algorithm and TEM technique. As a student major in materials science, he believe that with the development of AET technique, he can get the inner sight of materials under different behaviors, such as mechanism of Martensite transformation and growth of nano-materials. Besides research, Yao also likes playing basketball and tennis, as well as video games.
